80 kVA 20 kV Oil-immersed Power Transformer
I. Основной обзор
80 kVA 20 kV oil-immersed power transformer, mainly targeting medium-capacity high-voltage power distribution adaptation. The core is used for medium-sized industrial parks, outdoor power distribution hubs, photovoltaic power supply with medium power capacity, and high-voltage power distribution in small factories. It is compatible with 20 kV high-voltage power distribution systems, requiring no complex renovations, and can directly connect to existing power distribution lines, addressing the stable power supply needs of medium-capacity high-voltage power distribution, while also considering flexible deployment and durability, avoiding power waste or insufficient load issues.
II. Основные характеристики
Medium-capacity precise adaptation: With an 80 kVA capacity, it fits the scenarios of medium-sized industries and outdoor power distribution, meeting the power supply requirements of medium power, while avoiding power waste of large power equipment. Compared to ordinary Oil Immersed Transformers, it has a moderate size and flexible deployment, suitable for outdoor and small factory installations.
High-voltage long-term stability: Specifically designed for 20 kV high-voltage environments, during operation, the voltage is stable without fluctuations. The sealed oil-immersed structure combined with special insulating oil provides dust-proof, moisture-proof, and anti-interference capabilities, suitable for outdoor humid and dusty complex environments. It requires no frequent maintenance and reduces the later operation and maintenance costs.
Multifunctional compatibility adaptation: It can be seamlessly connected with Box Type Substation (box-type Transformer Station), High And Low Voltage Switchgear (high and low voltage switchgear), and can be combined with Electric Power Converter (electric power converter) to optimize power transmission efficiency. It can also be paired with Combined Photovoltaic Substations (photovoltaic Transformer Stations) to achieve medium-power photovoltaic power supply conversion without additional interface modifications.
III. Usage Tips
Installation does not require occupying too much space. Choose a flat and ventilated site, avoid damp and high-temperature areas, maintain a safe distance from High And Low Voltage Switchgear to ensure proper line connection.
Daily maintenance does not require professional personnel. Regularly observe the oil level and color of the insulating oil. A clear and unclouded color without odor indicates normal operation. Simple operations can be completed by ordinary people.
IV. Общие вопросы
Q: Can an 80 kVA capacity meet the daily power supply needs of small factories and outdoor power distribution hubs?
A: Absolutely, the 80 kVA capacity precisely adapts to small factories, outdoor power distribution hubs, and photovoltaic power supply with medium power capacity, can stably carry daily power supply loads, without power waste, and has no pressure during long-term operation.
Q: How is the waterproof and dustproof effect of the equipment when operating in an outdoor 20 kV high-voltage environment?
A: Excellent waterproof and dustproof effect. The sealed structure can effectively isolate rain and dust, suitable for outdoor complex environments. Even when exposed to the outdoors for a long time, there will be no issues such as moisture or short circuits, ensuring operational stability.
Q: Is there a significant difference in maintenance costs between this product and a transformer of the same capacity, Dry Type Transformer (dry-type transformer)?
A: There is a significant difference. Compared to Dry Type Transformer, this product does not require complex ventilation and cooling maintenance. Daily maintenance only requires checking the oil level, and the maintenance cost is lower. It also has better moisture-proof performance and is more suitable for outdoor scenarios.
